Guaranteed Operation 1.2V Op Amp and Reference on Single Chip Micropower: 130µA Supply Current Industrial Temperature Range SO-8 Packages Rail-to-Rail Output High Output Current: 20mA Min Output Drives 1000pF Capable of Floating Mode Operation Specified for 5V and ± 5V Supplies Low Reference Drift: 30ppm/°C Industry Standard LM10 Pinout
The is a new analog building block that includes a rail-to-rail output op amp, a precision reference and reference buffer. The device operates from supplies as low as a single ± 5V, yet it consumes only 130µA of supply current. The input common mode range of the op amp includes ground and incorporates phase reversal protection to prevent false outputs from occurring when the input is below the negative supply. The rail-to-rail output stage can swing to within 15mV of each rail with no load and can swing to within 250mV of each rail while delivering 10mA of output current. The gain bandwidth of the op amp is 175kHz and it is unitygain stable with to 1000pF load capacitance. The 0.2V reference is referred V and includes a buffer amplifier to enhance flexibility. The reference and buffer combine to achieve a drift 30ppm/°C, a line regulation of 20ppm/V and a load regulation of 150ppm/mA. The LT1635 is available in 8-pin PDIP and SO packages, and has the industry standard LM10 pinout.
